Abstract Scope |
Microcrack formation and propagation is highly dependent on the microstructure of the material and on the anisotropic material behavior. In this presentation, we summarize various recent developments in phase field fracture models that add the capability to model material anisotropy and its impact on brittle fracture at the mesoscale. We start by considering the impact of elastic anisotropy. We then include the impact of preferred cleavage planes. We end by considering thermal fracture induced by anisotropic thermal expansion coefficients. Simulations are carried out in 2D and 3D. All simulation results are obtained using the MOOSE framework. |
